At these prices, you really get dizzy. Especially since there are also additional costs. I wonder whether this will go on forever, or whether this bubble will eventually burst. In the future, the standard land value will also be included in the property tax. This means: even if someone has no intention of selling anything because they use it themselves, they will increasingly be asked to pay up, just because there are some people in the world who apparently are willing to pay any price for land in Germany. And then you also have to assume that the single-family house as such will be classified as "politically undesirable" in the medium term...
In return, my family has a huge plot of land in Berlin, with which we can practically do nothing else but mow the lawn, because the buildability ends immediately behind the existing buildings.
